P2090 Fault Code

B Camshaft Position Actuator Control Circuit Low Bank 1c

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2090 fault code indicates a problem with the camshaft position actuator control circuit for Bank 1c. This is related to the variable valve timing (VVT) system, which optimizes engine performance by adjusting the timing of the camshaft. A low signal in this circuit can lead to decreased engine efficiency and performance.

What are the symptoms of the P2090 code?

Symptoms associated with a P2090 error code may consist of:

• Reduced engine power or performance
• Rough idling or stalling
• Check Engine Light illumination
• Engine misfires or hesitation during acceleration
• Unusual engine noises from the timing components

What causes the P2090 code?

Common causes for the P2090 code include:

• Faulty camshaft position actuator
• Damaged wiring or connectors in the actuator control circuit
• Low engine oil level or dirty oil affecting actuator performance
• Malfunctioning Engine Control Module (ECM)
• Clogged VVT solenoid or passages

How to fix P2090?

To resolve the P2090 fault code, follow these steps:

• Check the engine oil level and quality; replace if necessary.
• Inspect wiring and connectors for damage or corrosion, repairing or replacing as needed.
• Test the camshaft position actuator and VVT solenoid for proper operation, replacing faulty components.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• If the problem persists, an in-depth diagnosis may be required to analyze the ECM and other related systems.
